Collar-button.



" To all whom it may concern.-

UNITED STATES PATENT OFFICE.

Be it known that I, HAROLD T. MURPHY, a

' citizen of the United States 'of America, and a resident of Springfield, in the countg of Hampden and State of Massachusetts, ave

invented certain new and useful Improvements in Collar-Buttons, of which the follow ing is a full, clear, and exact description.

This invention relates to improvements in collar-buttons, and more particularly to the class thereof comprising locking means cooperating with the back of the button for clamp- 4 is a sectional view as taken mg or binding the marginal portions of the collar or wrist band adjacent the buttonhole, whereby notwithstanding any enlargementof the buttonhole the button cannot become accidentally displaced.

The object of the invention is to improve collar-buttons of the class indicated to the end of acquiring simplicity and cheapness of construction and efiiciency and convenience of use. A

The invention consists in the constructions and combinations of parts and the formations .of certain of the parts, all substantially as hereinafter fully described, and set forth in the claims.

The improved collar-button is illustrated in the accompanying'drawings, in which Figure 1 is a side view thereof. Fig. 2 is a back view, the'portion of the supplemental section comprised in the back being broken away for clearer illustration. Fig. 3 is a sectional view as taken on line 3 3, Fig. 2. Fig. at right an les 3 and on the plane indicated by ine ig. 2/ Fig. 5 is a plan vievr of the main section of the back or back proper, together with a projected section thereof taken on line 5 5. Fig. 6 is a plan view of the flat spring comprised in the locking collarbutton,"and Fig. 7 is a perspective view of one of the T- shaped lever members.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the back proper, B the pos't,.and C the head of any suitable form and size and formed on or secured to the forward end of the post.

D D represent a pair of levers, the practical and specific form thereof being represented in Fig. 7, wherein it is clearly'seen that each lever is of T form, the cross members a a thereof being cross-sectionally square, while the to Fi.

of the transverse members a dis curved and the extremity (1 thereof widened.

The post as here shown is one having an arched base f to straddle the elongated aperture g in the back A, which aperture, as particularly shown in Fi s. 3 and 5, has its lo cation across the middle portion of the back and terminates within the opposite edge portions of such back, and the back, moreover,

is made with depressions i 'i at right angles to the length of the said aperture 9 and terminating at the opposite longitudinal boundaries thereof. These depressions are produced by sinking or displacing the thin metal from which'the back is constituted, and in order that these depressions may have the form of sufficiently deep troughs the'metal at the margins of the depressions is upset, as indicated at y', andin the acquirement of this specific formation the thin metal back-plate is made to assume the corrugated appearance most clearly represented in Fig. 5.

The T-shaped levers are assembled in relation to the back so that their curved portions 1) are disposed adjacent and through the re- 0 cess g, and the cross'members a a are seated in the channels or depressions i 'i, and the spring G is so applied behind the back A as to be pressed against by the corners of the lever cross members a a each time the levers are swung a quarter-way around, more or less.

The spring G, as shown, is of flat form, is

made of suitable thin metal, as steel or hard brass, and is anchored or in abutment at its ends and held against displacement and for its spring action at all times against the said members a a, which, as apparent, are in substance cams.

The back plate A is shown as having tongues h it struck up rearwardly from the 9 5 metal at the opposite marginal portions of such plate, which have interlocking engagement with the end recesses or niches 7c of the spring, so that the spring is constrained to remain always in its proper position of coaction with the cross members of the levers.

m represents a supplemental back, which may be of any suitable metal or material, made in the form of a shallow cup and hav ing the margins thereof return bent and over- 10 5.

lap on the front marginal portion of the main plate or back proper ofthe button which car- 'ries the head-provided post. This supplemental back firmly engaged with the main plate A by reason of its convexity or swell 11o creates between it and the plate A a thin chamber, giving sutlicient space for occupancy therein of the spring G and the lever members (1. (IV with clearance or freedom of dellcction oi the spring in consequence of the pressing of the parts a e having the cam-like actions relatively thereto.

The spring G of curved or how form and having its ends in abutment at the opposite portions of the wall of the inelosed chamber at the junctions ol the marginal portionsof the supplemental back with the main back plate is at all times ell'ective as a yielding resistance to the movements of the levers.

The utility and mode of operation of the devices comprised in this improved button will be readily apparent from the drawings and the description of the parts hereinabove given; but it will be briefly mentioned that the reaction between the spring behind the lni-cleplate and the lever cross members is such as to firmly retain the levers in either of their given set positions, shown in full lines in Fig. 3, wherein the levers have their ositions closely along the opposite sides ot the post as appropriate at the time of engagement of the button through the bnttonhole oi the garment, and shown by dotted lines in Fig. 3 and full lines in Fig. 1, wherein the le vers have their positions more or less nearly parallel with and suitably close to the back to clamp or bind the portions ol the l'abrie ;r, (which may be thaheom n'ised in a collar or wristband of a shirt,) adjacent the buttonhole 7 between the levers and the back.

in Fig. l the vertical parallel dotted lines at thej'ight of the dotted-liue representation of the shirt-collar band at are intended to indicate the overlapped buttonhole portions of a collar, and the dotted lines still l'urther to the right indicate a bow or necktie and the collar-blltton-eugagiug hook thereol'.

ll claim--- 1. [n a collar-button, a back lntving an aperture, a post having a head, a pair of T- shaped levers being capable of being disposed along and at opposite sides of the post having their portions adjacent the jinn-tions oi the levers proper and their cross members extended throu h said aperture, and having their cross members located behind the back, and a spring reacting behind the back and said cross members, and against which said cross members press on the swinging ol' the levers.
